Title: Heat transfer promoting device
Inventor: YAMADA YUKIO
IPC: F28F13/12
Filed: 1986-05-16
Abstract: PURPOSE:To obtain a device to promote heat transfer accompanied by a small pressure loss in the fluid without reducing the heat transfer promotion performance by constituting a heat transfer promotion device with a spiral plate which is devoid of its central section. CONSTITUTION:A heat transfer promoting device 2 is mounted in the inside of a heat transfer pipe 1. The device 2 is constructed with a spiral plate which is devoid of its central portion. The part to form a circulating flow which contributes mainly to heat transfer promotion is the peripheral section 4 in the spiral plate, and the circulating flow developed by the central portion 3 of the spiral plate does not much contribute to heat transfer promotion. Accordingly if a heat transfer promoting device 2 is formed by a spiral plate devoid of its central portion, the device's heat transfer performance is not reduced. On the other hand if the spiral plate has only the peripheral portion 4 without the central portion 3, the fluid flow resistance becomes smaller and the pressure loss is thereby small.

IPC: G01N29/44
Filed: 1992-05-06
Abstract: PURPOSE:To obtain an apparatus which executes a signal processing so that exfoliation of a coating film can be detected and thereby eliminates an error of visual determination. CONSTITUTION:In a detecting apparatus, a reflected wave received by an ultrasonic sensor 81 is amplified by an amplifier 11 and inputted to a clip circuit 12 for removing a voltage on the negative side.

Abstract: PURPOSE:To form a vapor-deposited film having magnetic anisotropy in the longitudinal direction on the film even if the film has the thickness uniform in the transverse direction by forming a control cylinder in such a manner that the inside peripheral wall surface of the control cylinder for controlling the splashing direction of metal vapor flow changes from a circular shape to elliptical shape toward the outlet direction of the vapor flow. CONSTITUTION:The shape of the control cylinder 7 which is disposed between a crucible 3 and a body 5 for vapor deposition and controls the splashing direction of the vapor flow is specified. Namely, the end face shape of the cylinder 7 opposite to the crucible 3 is circular and the end face shape opposite to the body 5 is the ellipse having >=2 ratio of the major axis to the minor axis. In addition, the projection of the cylinder 7 to the plane running the centers of the two end faces of the cylinder 7 is trapezoidal. The cylinder 7 is so formed that the vapor flow passing the inside of the cylinder is smoothly changed in the shape from the circular section to the elliptical section along the inside wall surface of the control cylinder 7 between the two end faces. Both the vapor deposition efficiency and film thickness distribution are thereby improved.

Filed: 1987-05-11
Abstract: PURPOSE:To prevent records from being superposed to each other by executing automatic control so that an image is formed in an area excluding a recorded area in transfer paper previously recording information on a part of its recording area. CONSTITUTION:The transfer paper P is sent by a paper feeding roll 22 and scanned by photosensors S1-Sn in a printing area detecting means 30 to detect light from a printed area and a non-printed area.

Abstract: PURPOSE:To measure exactly the quantity of FDP even in the presence of fibrinogen by applying a latex agglutination method for an anti-FDP (fibrinogen/ fibrin degradation product) monoclonal antibody which does not react with the fibrinogen. CONSTITUTION:Two kinds of anti-human FDP monoclonal antibodies are respectively added to a soln. prepd. by suspending polystyrene latex particles with a buffer soln. to prepare 03202 anti-human FDP monoclonal antibody sensitized polystyrene latex particles and 03204 anti-human FDP monoclonal antibody sensitized polystyrene latex particles. Both particles are then intimately mixed to prepare a sensitized latex for measurement. A specified quantity of such sensitized latex is thoroughly intimately mixed under oscillation with a specified quantity of a specimen such as serum or blood plasma on a slide plate or microtiter plate and the quantity of the FDP is measured from the presence or absence of agglutination image or the varied intensity thereof. The serum or blood plasma in which the fibronogen exists mixedly is thus made usable as the specimen.

Abstract: PURPOSE: To achieve higher reliability of the apparatus eliminating a local high temperature part in a metal temperature of the combustor by a method wherein an air hole or a slit are provided at an outlet end part of a premixed gas outlet port end part to let a part of air for combustion pass from the outer circumference side of the combustor to prevent adhesion as caused by the propagation of a flame. CONSTITUTION: A low NOx gas turbine combustor is a combination of a pilot burner 1 in a diffusive combustion and a main burner 9 in a premixed combustion. A flame holder 4 is provided on the downstream side of a premixer 2 of the main burner 9 to hold a premixed flame stably. An air hole 10 is provided on the end face on the downstream side of the premixer to let a part of air 5 for combustion pass from the outer circumference side of the combustor. The air 5 passes through the air hole 10 to eliminate a stagnant flow area thereby preventing adhesion as caused by the propagation of a flame. The air also passes through the stagnant flow area to lower the temperature and the concentration of a fuel thereby making the flame hard to propagate with a slowed speed of combustion.

Abstract: PURPOSE: To correct deflection distortion by opposedly arranging a pair of semicylindrical magnetic substance pieces on the front and rear ends of a deflection field with pincushion distortion between the vertical and horizontal axes.  
     CONSTITUTION: A pair of semicylindrical magnetic substance pieces 10 and 10' are opposedly arranged on the front end of a deflection field with pincushion distortion between them and the vertical axis y. A pair of semicylindrical magnetic pieces 12 and 12' are opposedly arranged on the rear end of the deflection field between them and the horizontal axis x. In this case, a deflected barrel type local magnetic field is generated in these magnetic substance pieces 10 and 10' and an electron beam 11 which received deflection by the deflection field receives both astigmatism and inverse astigmatism effects that are going to be received during the deflection field. On the other hand, an intense pincushion-type local magnetic field is generated in the magnetic substances 12 and 12' and the cosmetic aberration which is inverse to that which is received by the electron beam 11 is received. As a result, deflection aberration can be corrected.
